LinkedIn is where recruiters spend their time. That’s not the same as where placements come from. Source of hire is the metric that tells you whether those two things align \u2014 and for most firms, they don’t.<\/span><\/p>\n

This guide covers what source of hire is, what it actually measures, why the data most firms are sitting on tells a different story than they expect, how to build a report worth reading, and what to do with the findings once you have them.<\/span><\/p>\n

<\/span>What Is the Source of Hire?<\/span><\/span><\/h2>\n

The Metric That Tells You If Your Sourcing Is Working<\/span><\/h3>\n

Source of hire is a recruitment metric that tracks which channel or method originated each successful placement \u2014 LinkedIn, job boards, referrals, your existing database, direct outreach, events, or any other sourcing activity.<\/span><\/p>\n

The formula is straightforward:<\/span><\/p>\n\n\n\n

Source of Hire Formula<\/span><\/p>\n

Source of Hire % = (Hires from a specific source \u00f7 Total hires) \u00d7 100<\/span><\/p>\n

Example: 12 hires from referrals out of 60 total hires = 20% source of hire from referrals.<\/span><\/p><\/blockquote>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Where it gets more nuanced: source of hire should reflect where the relationship that led to the placement actually started \u2014 not just where the candidate’s application came in.\u00a0<\/span><\/p>\n

A candidate who found the role on Indeed but was already in your CRM from a conversation two years ago was sourced from your database, not from Indeed. That distinction matters when you’re making sourcing investment decisions.<\/span><\/p>\n

It sits within the broader framework of <\/span>recruiting metrics<\/span><\/a> and <\/span>recruitment KPIs<\/span><\/a> that drive operational decisions \u2014 not activity tracking.<\/span><\/p>\n

<\/span>Volume and Value Are Not the Same Sourcing Metric<\/span><\/span><\/h2>\n

LinkedIn dominates sourcing activity at most recruiting firms. That’s not surprising. But volume and value are different things.<\/span><\/p>\n

Recruiterflow’s analysis of operational data<\/span><\/a> across 2,100+ recruitment and executive search firms maps source of hire from initial contact through to placement. The findings challenge the assumption that the dominant sourcing channel is also the most productive one.<\/span><\/p>\n\n\n\n\n\n\n\n\n

LinkedIn’s source-to-submit rate is 5.11% \u2014 fewer than 6 in 100 candidates ever reach client submission. You need 283 LinkedIn-sourced candidates to produce one placement.<\/span><\/p>\n

Referrals: 9.26% source-to-submit, 78.92% interview-to-hire, 20 candidates per placement. The channel most firms treat as a secondary activity outperforms their primary one at every stage.<\/span><\/p>\n\n\n\n
The sourcing illusion<\/span><\/p>\n

Most recruiting firms are scaling inputs at the least efficient stage of the funnel. 213 candidates are sourced on average for every single hire. The instinct \u2014 more sourcing, more placements \u2014 is wrong. The constraint isn’t the top of the funnel. It’s conversion through it.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The database finding compounds this. Across the same dataset, 71% of placements came from candidates already in the CRM before the job order opened. The most valuable source of hire for most firms isn’t a channel they’re paying for.<\/span><\/p>\n

LinkedIn is a volume channel. Treating it as your primary source while underleveraging referrals and your existing database is an expensive allocation of recruiter time. Source of hire is the metric that makes that visible.<\/span><\/p>\n

<\/span>Garbage In, Garbage Out \u2014 How to Build a Source of Hire Report That Actually Means Something<\/span><\/span><\/h2>\n

The formula is simple. The challenge is data quality. Most firms that try to run a source of hire report discover the same problem: the source field in their ATS is inconsistently populated, candidates have multiple sources attributed, and the categories used six months ago don’t match the categories used today.<\/span><\/p>\n

Before you can use source of hire data to make decisions, the underlying data needs to be reliable.<\/span><\/p>\n

Step 1: Define your source categories and stick to them<\/span><\/h3>\n
